Last week's surprise release from Kendrick Lamar, untitled unmastered., is currently only available digitally. If you want to listen, you can buy it on iTunes or stream it places like Apple Music or Spotify. But if you go to, say, Best Buy, and look for the hard copy, you'd be out of luck.

That will soon change -- as soon as this week -- according to Anthony "Top Dawg" Tiffith, the founder and CEO of K. Dot's label, Top Dawg Entertainment.

CDs won't be the only option, though. Top says vinyl is on the way, too.

Even if you don't have a place to play the CD or the vinyl of this, it's worth considering grabbing one of these as a collector's item. I know I will.
